Answer:An acute angle is a type of angle that measures less than 90°. For example, when the time is 11 o'clock, the angle formed between the hour hand and the minute hand is an acute angle. In other words, 30°, 40°, 57°, and so on are all acute angles.
Step-by-step explanation:
4q^2 -(qr + 25); if q = 6 and r= 19
Answer:
5
Step-by-step explanation:
q = 6
r = 19
4q^2
= 4 x q^2
= 4 x 6^2
= 4 x 6 x 6
= 144
qr
= q x r
= 6 x 19
= 114
qr + 25
= 114 + 25
= 139
4q^2 - ( qr + 25 )
= 144 - 139
= 5

Which situation is an example of an observational study?
Answer:
D- Recording the reaction time of participants in a study who were asked to press a button as soon as they see a certain picture on a screen.
Step-by-step explanation:
The situation is an example of an observational study is "Recording the reaction time of participants in a study who were asked to press a button as soon as they see a certain picture on a screen:.
What is an observational study?When researchers monitor the effect of a risk factor, diagnostic test, therapy, or other intervention without attempting to influence who is or is not exposed to it in observational studies.
For example: Consider someone standing on a popular street in a New York neighborhood asking passers-by how many dogs they have, then analyzing the data to see if more pet food businesses are needed in the area.
As we know that in an observational study, the sample whose test/survey is been taken is completely random.
Therefore, the situation that is an example of an observational study is " Having customers fill out a questionnaire about their favorite brand of toothpaste".

plz help area is 54in
Answer:
equation: a/.5b=h
h=9
Step-by-step explanation:
a=1/2bh
divide both sides by 1/2b to get h alone
a/.5b=h
a/.5b=h
54/0.5(12)=h
54/6=h
9=h

Find an equation of the line parallel to y= 1/3x +1 and that passes through the point (3,5)
w(-3,3), x(6,4), y(6,-4) z(8,-6) determine weather wx and yz are paralell, perpindicular, or neither. PLEASE PLEEASE HELP ME
Answer:
Neither.
Step-by-step explanation:
Parallel lines have equivalent slopes while perpendicular lines have opposite reciprocal slopes. (Opposite meaning different signs and reciprocal meaning flipped fraction)
Ex: 3/4 → -4/3[tex]wx:~m=\frac{4-3}{6-(-3)}\\wx:~m=\frac{1}{9}\\\\yz:~m=\frac{-6-(-4)}{8-6}\\yz:~m=\frac{-2}{2}\\yz:~m=-1[/tex]
These lines are neither parallel nor perpendicular.
Find the slope of the line that passes through the points (4,1) and (-2.7).
What is the slope of a line perpendicular to this line?
Answer:
the slope=-1 the slope perp=1
Step-by-step explanation:
to find slope perpendicular you just have to multiply your slope by something and have it equal -1
for example
1/2x=-1
the slope perpendicular to a line with the slope of 1/2 would be -2 beacause 1/2x-2=-1
so the slope x perpendicular slope = -1
A stuntman falls from the top of a building 26 ft above the ground. The function h (t) -16t^2+26
gives the height of the man in feet after t seconds.
Answer:
let h(t)= 0 (because when it reaches the ground h=0)
0=-16t^2+116
16t^2=116
divide both sides by 16
t^2= 7.25
square root both sides to find t
t=2.69sec

write 5 square root values that are between 9 and 10 explain your strategy
Answer:
sqrt(x) where x is between 81 and 100; example sqrt(88). See explanation for more examples.
Step-by-step explanation:
9=sqrt(81) and 10=sqrt(100)...
So the square root(x) is between 9 and 10 if x is between 81 and 100.
Here are examples:
sqrt(82)
sqrt(83)
sqrt(85.6)
sqrt(92)
sqrt(94)
sqrt(97)
sqrt(99)
sqrt(99.6)
So again the answer is just anything in form sqrt(x) where x is between 81 and 100. The reasoning is because sqrt(81)=9 and sqrt(100)=10 which puts the values we stated between those values.

Given, consecutive / adjacent angles in a parallelogram are supplementary or make 180°. So, here (5a + 34)° & (3a + 26)° are supplementary angles.
=》5a + 34 + 3a + 26 = 180
=》5a + 3a + 34 + 26 = 180
=》8a + 60 = 180
=》8a = 120
=》a = 120/8
=》 a = 15

David made an error when determining the product of (–2.5)(–8.3).
Step 1: (–2.5)(–8.3) = (–8.3)(–2.5)
Step 2: = (–8.3)(–2) + (–8.3)(–0.5)
Step 3: = (–16.6) + (–4.15)
Step 4: = –20.75
In which step did David make his first error?
Answer:
step 3
Step-by-step explanation:
when you multiply an even amount of negative numbers you will always get a positive result thus the answe would be 16.6 + 4.15 as in positive numbers

Two shops, Lidal and Oldi, sell the same brand of toilet rolls but with different package sizes.
Calculate the price per roll for each shop.
Write which shop is the best value for money in the comment box.
Step-by-step explanation:
Lidal : 9 rolls for £3.51
1 roll for 3.51/9 = £0.39
Oldi : 4 rolls for £1.52
1 roll for 1.52/4 = £0.38
so, Oldi has the best value for money when buying toilet rolls.
